Tree up to 35 m tall, hemi-epiphytic or (secondarily?) terrestrial. Branches drying brown to greyish. Leafy twigs 4-7 mm thick, ± angular, densely (dark) brown (to whitish) floccose-tomentose, glabrescent; periderm persistent. Leaves spirally ar-ranged; lamina oblong to elliptic to subobovate (to oblanceolate), (5-)10-20(-27) by (2.5-)4-9(-14) cm, coriaceous, apex short-acuminate to rounded, base rounded to obtuse or to subcordate; upper surface brown tomentose, mainly on the lower part and on the main veins, glabrescent (or glabrous?), lower surface brown floccose-tomentose, glabrescent; cystoliths on both sides; midrib (at least the lower part) ± impressed above, lateral veins (4-)5-7 pairs, the basal pair distinct, up to 1/4-1/3(-1/2) the length of the lamina, branched, usually 1 pair of smaller lateral veins below the main pair, tertiary venation reticulate (to subscalariform), prominent beneath; waxy gland at the base of the midrib; petiole 1-3(-6) cm long, 2-3 mm thick, densely brown floccose-tomentose, glabrescent, drying brown to blackish; stipules 1-2(-6) cm long, ± densely brown to greyish floccose-tomentose (to-subvillous), caducous (or subpersistent). Figs axillary, paired (or solitary), sessile, calyptrate bud covers absent (?); basal bracts 3, 4-8 mm long, ± unequal, (1 or) 2 with a distinct median part (or keeled), puberulous on the median part or glabrous, persistent; receptacle (depressed-)subglobose, 0.8-1.2(-1.5) cm diam. when dry, brown tomentose, glabrescent, orange to dark red at maturity, apex ± convex to submammillate, ostiole 3-5 mm diam., flat to prominent, closed, the 3 upper ostiolar bracts fully imbricate; wall ± shrivelled when dry; internal hairs absent. Tepals reddish. Ovary red.
Undisturbed mixed dipterocarp, (peat)-swamp, coastal and sub-montane forests at elevations up to 800 metres. On alluvial sites (swamps) but also common on ridges and hillsides. In secondary forests usually as a pre-disturbance remnant tree.
